A locking hole 38 passing through the plate surface is provided in the locked piece 37 at a position facing the proximal end side portion 33 of the locking piece 32 when the folded portion 35 is folded back. The locking hole 38 has an isosceles trapezoid shape, and its lower base is arranged inside the second flange covering part 36 in the extending direction (on the right side in FIG. 4), and its upper base is longer than the lower base. It is formed to be disposed on the outside (left side in FIG. 4).

係止片３２および係止孔３８について図５を参照してより詳細に説明すると、係止孔３８のうち上底の寸法をｃ、上底を除いた孔縁部（下底と２つの対辺の合計）の寸法をａ、一の対辺の寸法をｅとし、係止片３２のうち先端側部の下底の寸法をｂ、高さ寸法をｄ、板厚をｆとすると、次の関係が成り立つように各寸法が設定されている。
ａ＞ｂ＞ｃ かつ ｄ＞ｅ＞ｆ …（式１）
このような関係を満たすことにより、係止片３２が係止孔３８内に挿入可能となり、かつ、係止孔３８の孔縁部に係止可能とされる。 The locking piece 32 and the locking hole 38 will be explained in more detail with reference to FIG. ) is the dimension of a, the dimension of one opposite side is e, the dimension of the bottom of the tip side of the locking piece 32 is b, the height is d, and the plate thickness is f, then the following relationship is given. Each dimension is set so that the following holds true.
a>b>c and d>e>f...(Formula 1)
By satisfying such a relationship, the locking piece 32 can be inserted into the locking hole 38 and can be locked to the edge of the locking hole 38.

このようなサイレンサ２０をリアホイールハウスパネル１０に対して取り付け可能に組み立てる際には、まず、折り返し部３５を山折りに折り返すとともに、第１被覆部２３および第１フランジ被覆部３１の境界部２５と、第２被覆部２４および第２フランジ被覆部３６の境界部２６を谷折りに折って、各フランジ被覆部３１，３６を各被覆部２３，２４から立ち上げた状態とする。次に、係止片３２の先端側部３４を湾曲させつつ係止孔３８内に差し込み、貫通させた後に弾性復帰させて係止孔３８の孔縁部に引っ掛けて係止する。これにより、第１被覆部２３および第２被覆部２４から立ち上がるとともに両端部が閉じられた袋状の突条部被覆部３０が形成される。 When assembling such a silencer 20 so that it can be attached to the rear wheel house panel 10, first, the folded portion 35 is folded back into a mountain fold, and the boundary portion 25 between the first covering portion 23 and the first flange covering portion 31 is folded back. Then, the boundary portion 26 between the second covering portion 24 and the second flange covering portion 36 is folded into a valley fold, so that each flange covering portion 31, 36 stands up from each covering portion 23, 24. Next, the distal end portion 34 of the locking piece 32 is inserted into the locking hole 38 while being curved, and after passing through the locking piece 32, the locking piece 32 is elastically returned and hooked onto the edge of the locking hole 38 to be locked. As a result, a bag-shaped protrusion covering portion 30 is formed that rises from the first covering portion 23 and the second covering portion 24 and has both ends closed.

なお、このような組み立て時に、係止片３２の係止孔３８に対する係止状態や、折り返し部３５および境界部２５，２６の折り曲げ状態が、サイレンサ２０の弾性復帰力によりもとの平坦な状態に戻り難くするために、突条部被覆部３０に予めプレス成形を施しておくことが好ましい。 In addition, during such assembly, the locked state of the locking piece 32 in the locking hole 38 and the folded state of the folded portion 35 and the boundary portions 25 and 26 are returned to the original flat state due to the elastic return force of the silencer 20. In order to make it difficult to return to the original shape, it is preferable to press-form the protrusion covering portion 30 in advance.

具体的には、図３に示すように、係止片３２の基端側部３３を、折り返し部３５を折り曲げた際に被係止片３７に向けて近づく方向に傾斜させ、被係止片３７のうち係止孔３８を含む位置から基端側の部分を、係止片３２に向けて近づく方向に傾斜させる構成とすることで、係止片３２を係止孔３８に挿入し易くするとともに、係止孔３８に挿通された係止片３２の係止状態を安定的に保つことができる。また、係止片３２の先端側の板厚を薄くして湾曲し易くすることによっても、係止片３２を係止孔３８に挿入し易くすることができる。 Specifically, as shown in FIG. 3, the proximal end portion 33 of the locking piece 32 is tilted in a direction approaching the locked piece 37 when the folded portion 35 is bent, so that the locked piece 37, a portion on the proximal end side from a position including the locking hole 38 is configured to be inclined in a direction approaching the locking piece 32, thereby making it easier to insert the locking piece 32 into the locking hole 38. At the same time, the locked state of the locking piece 32 inserted into the locking hole 38 can be stably maintained. Further, the locking piece 32 can be easily inserted into the locking hole 38 by making the plate thickness on the front end side of the locking piece 32 thinner to make it easier to curve.

次に、作用効果を説明する。本実施形態のサイレンサ２０の取り付け構造は、板面から突出する突条部１５を有するリアホイールハウスパネル１０に対してマット状のサイレンサ２０を取り付ける構造であって、サイレンサ２０は、第１パネル１１および第２パネル１３の板面を被覆する第１被覆部２３および第２被覆部２４と、第１被覆部２３および第２被覆部２４から立ち上がるとともに折り返されて、突条部１５の一面側を被覆する第１フランジ被覆部３１および他面側を被覆する第２フランジ被覆部３６と、を有しており、第１フランジ被覆部３１の延び方向における両端部に、当該両端部から延び出す係止片３２が設けられ、第２フランジ被覆部３６の両端部に、当該両端部から延び出すとともに係止片３２を係止可能な被係止片３７および係止孔３８が設けられ、第１フランジ被覆部３１および第２フランジ被覆部３６は、係止片３２が係止孔３８に係止することにより、突条部１５を被覆可能な袋状に連結されている。 Next, the effects will be explained. The mounting structure of the silencer 20 of this embodiment is a structure in which the mat-like silencer 20 is mounted to the rear wheel house panel 10 having the protrusion 15 projecting from the plate surface, and the silencer 20 is mounted on the first panel 11. and a first covering part 23 and a second covering part 24 that cover the plate surface of the second panel 13, and a first covering part 23 and a second covering part 24 that rise from the first covering part 23 and second covering part 24 and are folded back to cover one side of the protrusion part 15. It has a first flange covering part 31 to cover and a second flange covering part 36 to cover the other side, and has engagements extending from both ends at both ends in the extending direction of the first flange covering part 31. A locking piece 32 is provided, and a locking piece 37 and a locking hole 38 that extend from both ends and are capable of locking the locking piece 32 are provided at both ends of the second flange covering portion 36, and a locking hole 38 is provided at both ends of the second flange covering portion 36. The flange covering portion 31 and the second flange covering portion 36 are connected in a bag shape that can cover the protrusion portion 15 by the locking piece 32 locking into the locking hole 38 .

上記構成によれば、サイレンサ２０を取り付けるリアホイールハウスパネル１０が板面から突出する突条部１５を有する場合でも、副資材を使用することなくサイレンサ２０の一部に板面から立ち上がる袋状の部分を形成し、この袋状の部分で突条部１５を覆うことができる。つまり、単一の材料で構成されたリサイクル性に優れたサイレンサ２０を提供することができる。 According to the above configuration, even when the rear wheel house panel 10 to which the silencer 20 is attached has the protrusion 15 protruding from the plate surface, a bag-shaped part that rises from the plate surface is formed on a part of the silencer 20 without using any auxiliary materials. This bag-shaped portion can cover the protrusion 15. In other words, it is possible to provide a silencer 20 that is made of a single material and has excellent recyclability.

係止片３２は、先端側が基端側部３３から張り出して幅広とされた先端側部３４とされており、係止孔３８は、先端側部３４より幅狭とされて先端側部３４を係止可能とされている。 The locking piece 32 has a wide distal end portion 34 that protrudes from the proximal end portion 33 on the distal end side, and the locking hole 38 is narrower than the distal end side portion 34 and extends from the proximal side portion 34.
